Data tracing in Tuner Pro...

Tuesday, April 9, 2019 - 08:00

As I posted recently the data logger project has been taking up a lot of my time over the past few months.

The main intention of the logger is to enable faster, configurable data logging which can be saved into either CSV or Tuner Pro XDL formats.

Over the past few weeks I've been doing a bit of work on reverse engineering Tuner Pro's XDL data log format. I got about 95% worked out before I got in touch with Tuner Pro developer Mark Mansur who very kindly pointed out with the parts I'd got wrong and filled in the bits I couldn't figure out.

As a way of developing and testing the ADX writer code on the desktop, I've written a bunch of code that reads in an ADX file and Nanocom log file (from an Nanocom running current firmware) and uses that information to create an XDL log file.

There are some issues like the lack of Throttle % in the EVO logs that makes the convertor less useful than it should be.

As a teaser to show the possibilities ADX logging opens up this screen capture shows TP data tracing a converted Nanocom EVO log.
The MAF airflow calculation is being done in Tuner Pro RT, and a simple monitor setup shows AAP and MAP.
